Keyboardion

I had another idea for a musical instrument, and I think it worked out pretty well. It’s sort of a cross between a chromatic button accordion and a keytar. Or maybe it’s a digital Chapman Stick… except that it’s more polyphonic and tuned completely differently. I don’t know. It’s kind of a new thing, I think. The chromatic button accordion is probably the oldest and certainly the most popular isomorphic keyboard instrument in the world, so it’s not that much of a new thing. But as far as I know, the keyboardion is the first instrument that adapts its tuning to this particular form factor.1 All of the digital isomorphic keyboards that I know about have more of a square aspect ratio,2 and they’re usually designed to be played like a piano or a concertina: both hands symmetrically engaged with the keyboard. But I was really curious how this asymmetry would feel: the left hand probably plays in the bass register, so it can accompany the melody with chords. The left hand is pretty good at…
